I <3 this song. Hard looks pretty nice to me, just a few suggestions on it...
00:47:38 (1,2) - I think these circles require more emphasis than they currently have. Putting in Normal Finish hit sounds instead of the Soft Finish makes it sound better imo.
The following requires more emphasis as well. The same suggestion as above, but also put the following circles on top of each other to emphasize them more, like you did with 00:47:38 (1,2).
In other words stack these (and add hitsounds):
00:48:838 (5,6)
00:50:552 (5,6)
00:48:838 (5,6)
00:53:992 (1,2) - Move the 1 down to the position of the 2.
The same suggestion for when it re-occurs at 01:59:123.
00:57:623 (2,3,4) - The stack and transition to the slider doesn't feel natural. Imo, it would be better if you moved the stack onto the slider so it's a stack of 4, and then move the slider a bit to the right and up to keep the flow.
02:35:552 (1 - 6) - This sounds fine and does work. If you wanted to follow every word, there should be a circle on 02:35:445 to start off the combo. I dunno if you left it out, because it decreases the time you have to jump to there. Maybe it fits better in an insane than a Hard.
That's all I have for now~
